Sidelink Communication Method and Terminal Device

2. The method according to claim 1, wherein, in response to the resource indication information of the sidelink reference signal comprising time domain symbol indication information of the sidelink reference signal but not slot indication information of the sidelink reference signal, the sidelink reference signal and a physical sidelink control channel (PSCCH) carrying the SCI are in a same slot.

3. The method according to claim 1, wherein the sidelink reference signal comprises sidelink channel state information reference signal (CSI-RS).

4. The method according to claim 1, wherein, in response to the SCI being in a first SCI format, the first indication field in the SCI is used for indicating the first terminal device to determine the resource indication information of the sidelink reference signal.

5. The method according to claim 1, wherein, in response to the SCI being in a second SCI format, the SCI does not comprise the resource indication information of the sidelink reference signal.

7. The method according to claim 6, wherein, in response to the resource indication information of the sidelink reference signal comprising time domain symbol indication information of the sidelink reference signal but not slot indication information of the sidelink reference signal, the sidelink reference signal and a physical sidelink control channel (PSCCH) carrying the SCI are in a same slot.

8. The method according to claim 6, wherein the sidelink reference signal comprises sidelink channel state information reference signal (CSI-RS).

9. The method according to claim 6, wherein, in response to the SCI being in a first SCI format, the first indication field in the SCI is used for indicating the first terminal device to determine the resource indication information of the sidelink reference signal.

10. The method according to claim 6, wherein, in response to the SCI being in a second SCI format, the SCI does not comprise the resource indication information of the sidelink reference signal.

12. The terminal device according to claim 11, wherein, in response to the resource indication information of the sidelink reference signal comprising time domain symbol indication information of the sidelink reference signal but not slot indication information of the sidelink reference signal, the sidelink reference signal and a physical sidelink control channel (PSCCH) carrying the SCI are in a same slot.

13. The terminal device according to claim 11, wherein the sidelink reference signal comprises sidelink channel state information reference signal (CSI-RS).

14. The terminal device according to claim 11, wherein, in response to the SCI being in a first SCI format, the first indication field in the SCI is used for indicating the first terminal device to determine the resource indication information of the sidelink reference signal.

15. The terminal device according to claim 11, wherein, in response to the SCI being in a second SCI format, the SCI does not comprise the resource indication information of the sidelink reference signal.
